Levofloxacin tablets can effectively improve the symptoms of bronchitis and are convenient to use, which is favored by many patients. Below, I will introduce to everyone: how many tablets of levofloxacin should be taken at one time? 　

Levofloxacin tablets are white plastic film-coated tablets, which appear creamy white or light yellow after removing the plastic film. The main ingredient is levofloxacin hydrochloride, which inhibits the replication of bacterial DNA by inhibiting the specificity of bacterial DNA gyrase (bacterial topoisomerase II). Dosage and administration: oral, 0.5g (1 tablet) once a day for adults. 　

Levofloxacin tablets are used for mild to moderate infections caused by relatively sensitive bacteria: 1. Respiratory tract infections: subacute sinusitis, chronic bronchitis with acute onset, community-acquired pneumonia; 2. Urinary and reproductive system infections: subacute pyelonephritis, multiple urinary tract infections, etc.; 3. Urinary system infections: prostatitis, epididymitis, intrauterine infection, adnexitis, pelvic inflammatory disease (when suspected to be infected with Pseudomonas aeruginosa, it can be used with omeprazole). 　

When using levofloxacin tablets, attention should be paid: Quinolone drugs can also cause rare shock, allergic symptoms, toxic side effects such as skin necrosis, subacute renal insufficiency, jaundice, granulocytopenia, leukopenia, hemolytic anemia, interstitial pneumonia, pseudomembranous colitis, and severe colitis with purulent and bloody stools. In addition, there are occasional reports of rhabdomyolysis, hypoglycemia, Achilles tendinitis or Achilles tendon rupture, mental disorder, and allergic vasculitis after taking the medicine. Therefore, if the described symptoms occur, the medicine should be discontinued immediately and appropriate treatment should be carried out until the symptoms subside.
